    Importance: Identifing potential screening tests for future cognitive decline is a priority for developing treatments for and the prevention of dementia.

    Objective: To examine the potential of retinal nerve fiber layer (RNFL) thickness measurement in identifying those at greater risk of cognitive decline in a large community cohort of healthy people.

    Design, Setting, and Participants: UK Biobank is a prospective, multicenter, community-based study of UK residents aged 40 to 69 years at enrollment who underwent baseline retinal optical coherence tomography imaging, a physical examination, and a questionnaire. The pilot study phase was conducted from March 2006 to June 2006, and the main cohort underwent examination for baseline measures from April 2007 to October 2010. Four basic cognitive tests were performed at baseline, which were then repeated in a subset of participants approximately 3 years later. We analyzed eyes with high-quality optical coherence tomography images, excluding those with eye disease or vision loss, a history of ocular or neurological disease, or diabetes. We explored associations between RNFL thickness and cognitive function using multivariable logistic regression modeling to control for demographic as well as physiologic and ocular variation.

    Main Outcomes and Measures: Odds ratios (ORs) for cognitive performance in the lowest fifth percentile in at least 2 of 4 cognitive tests at baseline, or worsening results on at least 1 cognitive test at follow-up. These analyses were adjusted for age, sex, race/ethnicity, height, refraction, intraocular pressure, education, and socioeconomic status.

    Results: A total of 32 038 people were included at baseline testing, for whom the mean age was 56.0 years and of whom 17 172 (53.6%) were women. A thinner RNFL was associated with worse cognitive performance on baseline assessment. A multivariable regression controlling for potential confounders showed that those in the thinnest quintile of RNFL were 11% more likely to fail at least 1 cognitive test (95% CI, 2.0%-2.1%; P = .01). Follow-up cognitive tests were performed for 1251 participants (3.9%). Participants with an RNFL thickness in the 2 thinnest quintiles were almost twice as likely to have at least 1 test score be worse at follow-up cognitive testing (quintile 1: OR, 1.92; 95% CI, 1.29-2.85; P < .001; quintile 2: OR, 2.08; 95% CI, 1.40-3.08; P < .001).

    Conclusions and Relevance: A thinner RNFL is associated with worse cognitive function in individuals without a neurodegenerative disease as well as greater likelihood of future cognitive decline. This preclinical observation has implications for future research, prevention, and treatment of dementia.

    The research took place at the National Institute for Health Research (NIHR) Biomedical Research Centre at Moorfields Eye Hospital NHS Foundation Trust and UCL Institute of Ophthalmology.

      Intelligent epidural needle placement using fiber-probe optical coherence tomography in a piglet model

      Incorrect needle placement during an epidural block causes medical complications such as dural puncture or spinal cord injury. We propose a system combining an optical coherence tomography imaging probe with an automatic identification algorithm to objectively identify the epidural needle-tip position and thus reduce complications during epidural needle insertion. Eight quantitative features were extracted from each two-dimensional optical coherence tomography image during insertion of the needle tip from the skin surface to the epidural space. 847 in vivo optical coherence tomography images were obtained from three anesthetized piglets. The area under the receiver operating characteristic curve was used to quantify ...

      Objectives This study aimed to determine the effect on long-term survival of using optical coherence tomography (OCT) during percutaneous coronary intervention (PCI). Background Angiographic guidance for PCI has substantial limitations. The superior spatial resolution of OCT could translate into meaningful clinical benefits, although limited data exist to date about their effect on clinical endpoints . Methods This was a cohort study based on the Pan-London (United Kingdom) PCI registry, which includes 123,764 patients who underwent PCI in National Health Service hospitals in London between 2005 and 2015. Patients undergoing primary PCI or pressure wire use were excluded leaving 87,166 ...

      Will Optical Coherence Tomography Become the Standard Imaging Tool for Percutaneous Coronary Intervention Guidance?

      Editorial Comment: In the last 3 decades, intravascular ultrasound (IVUS) and, more recently, optical coherence tomography (OCT) have been increasingly used to guide percutaneous coronary intervention (PCI). Although there are randomized trials, registries, and meta-analyses suggesting better outcomes using IVUS to guide PCI (1–3), data on the clinical impact of OCT are still missing. In the United Kingdom, consecutive data of all PCI procedures must be prospectively entered in the registry organized by the British Cardiovascular Interventional Society, endorsed by the United Kingdom Department of Health, with tracking of events based on the complete and unquestionable national statistics.

      Spatially confined quantification of bilirubin concentrations by spectroscopic visible-light optical coherence tomography

      Spatially confined measurements of bilirubin in tissue can be of great value for noninvasive bilirubin estimations during neonatal jaundice, as well as our understanding of the physiology behind bilirubin extravasation. This work shows the potential of spectroscopic visible-light optical coherence tomography (sOCT) for this purpose. At the bilirubin absorption peak around 460 nm, sOCT suffers from a strong signal decay with depth, which we overcome by optimizing our system sensitivity through a combination of zero-delay acquisition and focus tracking. In a phantom study, we demonstrate the quantification of bilirubin concentrations between 0 and 650 µM with only a 10% difference ...

      Three-dimensional graph-based skin layer segmentation in optical coherence tomography images for roughness estimation

      Automatic skin layer segmentation in optical coherence tomography (OCT) images is important for a topographic assessment of skin or skin disease detection. However, existing methods cannot deal with the problem of shadowing in OCT images due to the presence of hair, scales, etc. In this work, we propose a method to segment the topmost layer of the skin (or the skin surface) using 3D graphs with a novel cost function to deal with shadowing in OCT images. 3D graph cuts use context information across B-scans when segmenting the skin surface, which improves the segmentation as compared to segmenting each B-scan ...

      Late clinical outcome of suboptimal stent implantation defined by intracoronary optical coherence tomography

      Optical coherence tomography (OCT) is an intravascular imaging technique that provides high-resolution (10-20 μm) images. During percutaneous coronary intervention (PCI), OCT offers useful information to guide treatment strategies and assess optimal stent implantation (Figure 1) . However, OCT remains markedly underused in the real world. For further integration of OCT into clinical practice, it is necessary to accumulate evidence showing that OCT has a beneficial impact on the outcomes of PCI. In 2012 and 2015, Prati et al 1,2 reported the clinical benefits of OCT guidance in PCI using data

We are thrilled to receive marketing clearance for our innovative AngioAnalytics technology as part of the AngioVue System to aid physicians in the early detection and management of sight-threatening eye diseases in the U.S.,” said Jay Wei, founder and chief executive officer of Optovue. “Analytic measurement tools will shift the treatment paradigm because they provide an objective measure of treatment efficacy, thereby enabling truly customized patient management and improved patient care...The information provided by AngioAnalytics may help to change the clinical management of diabetic retinopathy, age-related macular degeneration and other diseases that progressively cause blindness for millions of people. We will continue to advance AngioAnalytics as we believe quantification is the gateway to widespread and global adoption of OCTA.
